Abstract
A defibrating device and sheet manufacturing apparatus attract and remove metal fragments when metal fragments are mixed with fibrous material. A defibrating device has a main unit with a defibration section configured to defibrate fibrous material, and a swirl section configured to produce a rotational current, and by the rotational current cause the fibrous material to rotate and flow into the defibration section. The main unit has a magnet unit that is disposed to the swirl section, and has a magnet that attracts by magnetic force metal fragments conveyed with the fibrous material to the swirl section.
Claims20
A defibrating device comprising:
- a main unit including:
- a defibration section configured to defibrate fibrous material;
- a swirl section configured to produce a rotational current, and by the rotational current cause the fibrous material to rotate and flow into the defibration section;
- and
- a magnet unit disposed on the swirl section, the magnet unit including a magnet that attracts by magnetic force metal fragments conveyed with the fibrous material to the swirl section.
A defibrating device comprising:
- a suction port through which fibrous material is suctioned;
- a cylinder portion that communicates with the suction port;
- an inside circumference part disposed along an inside surface of the cylinder portion;
- a defibration section that
- communicates with the inside circumference part with the proviso that the fibrous material introduced to the inside circumference part is rotated by a rotational current being produced by a swirl section of the defibrating device, to flow into the defibration section, and
- defibrates the fibrous material;
- and
- a magnet unit disposed on the inside circumference part and configured to attract by magnetic force metal fragments conveyed with the fibrous material to the inside circumference part.
A defibrating device comprising:
- a defibration section configured to defibrate fibrous material;
- and
- a magnet unit located upstream of the defibration section such that the fibrous material passes the magnet unit before the fibrous material is fed into the defibration section, with the proviso that the fibrous material is fed into the defibration section by being rotated by a rotational current being produced by a swirl section of the defibrating device, to flow into the defibration section.
